Title: Pad dyeing of cotton fabric with natural dyes from oak leaves
Abstract: A natural dye is extracted from oak leaves,its stabilities to Fe2+、Cu2+、Al3+ ions and pH value are studied,and then is applied to pad dyeing of cotton fabric.The influences of the kind and dosage of mordant agent,curing temperature and time on dyeing results are discussed.The results show that the oak leaves dye is stable to weak acid and metal ions,and is sensitive to alkaline(pH8) conditions.The optimum pad dyeing process with oak leaves dyes is as follows: post mordant dyeing with ferrous sulfate 15 g/L,curing at 135 for 2.5 min.The cotton dyeings feature good color yield and color fastness to soaping and rubbing.
